Skyworks Solutions Inc. SKY55951-11 Front-End Module (FEM)

Skyworks Solutions Inc. SKY55951-11 Front-End Module (FEM) features an integrated L1 low-noise amplifier (LNA) and post-filter along with an L5 LNA and post-filter designed for Global Navigation Satellite System (GNSS) receiver applications. Part of the Sky5® portfolio, the SKY55951-11 provides high gain, low current consumption, and integrated input and output matching for L1 and L5, all in a compact package.

The L1 path also features an integrated B13 notch filter, providing excellent suppression (-50dBm) of cellular low-band second harmonic signals impacting GPS L1 reception. The post-filtering on the L5 path also provides high (> 45dBc) out-of-band rejection for interference below 1GHz. The Skyworks Solutions Inc. SKY55951-11 uses surface-mount technology (SMT) in a Multi-Chip Module (MCM), a proven and highly manufacturable solution.
